It carries the DCMT 11 T3 04-UM 2025 ISO designation and belongs to the CoroTurn 107 series. The insert features a multilayer TiCN, Al2O3, and TiN coating over a carbide substrate, providing thermal resistance and wear protection during continuous and interrupted cuts. At 0.442 inches in length with a 3\/8 inch inscribed circle and a 1\/64 inch corner radius, this insert is sized for light-to-medium turning passes. It delivers two cutting edges per insert, making efficient use of tooling cost per edge.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for machining stainless steel workpieces, consistent with the ISO M workpiece material code. The UM chip breaker geometry is suited for finishing and semi-finishing operations where chip control and surface finish are critical. The insert seats via screw clamping, standard on CoroTurn 107 toolholders. It is installed by machinists and CNC tooling technicians in production turning environments handling austenitic and other stainless steel grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiCN, Al2O3, and TiN multilayer coating for extended tool life on stainless steel\u003c\/li\u003e\n  \u003cli\u003eUM chip breaker geometry optimized for finishing and semi-finishing cuts with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (DCMT) provides two usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch corner radius suited for tight-tolerance finishing operations\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.442 inches supports a range of light and medium turning passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroTurn 107 series screw-clamp toolholders that accept DCMT-style inserts.

Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert pocket for chips or contamination before seating the insert, as debris under the insert will affect cutting geometry and can cause premature failure. Always index or replace the insert before cutting edge condition degrades to the point of workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCMT 11 T3 04-UM 2025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55 Degree Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches (5\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5730989\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51747953639730,"sku":"5730989","price":275.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3502416c38379be0c53c1e01174e8dfc_39dd97fb-bf85-444a-99e5-b5525e600311.jpg?v=1788887419","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730989-turning-insert-dcmt32-51-um-2025","provider":"Voomi Supply","version":"1.0","type":"link"}
